Protein beverages

ABSTRACT

Provided herein are protein beverages. In particular, provided herein are protein beverages that are thickened, stable, and ready to drink beverages designed for consumption by subjects (e.g., subjects having a need for thickened beverages). In some embodiments, the subjects are subjects having dysphagia.

The present application is a continuation of U.S. patent application Ser. No. 15/588,224, filed May 5, 2017, now U.S. Pat. No. 9,930,906, the disclosure of which is herein incorporated by reference in its entirety.

FIELD

Provided herein are protein beverages. In particular, provided herein are protein beverages that are thickened, stable, and ready to drink beverages designed for consumption by subjects (e.g., subjects having a need for thickened beverages). In some embodiments, the subjects are subjects having dysphagia.

BACKGROUND

Dysphagia, the medical term for difficulty in swallowing, affects more than 18 million adults and millions more children in the U.S. Dysphagia is associated with increased mortality and morbidity. Patients with dysphagia suffer from many chronic problems including dehydration, pulmonary complications, reduced quality of life, and malnutrition. Sarcopenia, the age-related loss of muscle mass, is a primary cause of dysphagia and is exacerbated by malnutrition. Malnutrition-Sarcopenia syndrome is a chronic affliction among older adults, resulting of their decreased swallowing function. In addition to age-related sarcopenia, muscle weakness leading to dysphagia can be caused by other health problems such as stroke, neurodegenerative diseases, and cancer. One of the most common treatment strategies for dysphagia is drinking dietary beverages that are thickened. Although muscle weakness can be attenuated with adequate protein intake, current thickened dietary beverages for dysphagia primarily provide carbohydrates and contain little or no protein.

What is needed are dietary beverages for dysphagia that provide protein.

SUMMARY

DETAILED DESCRIPTION

Provided herein are protein beverages. In particular, provided herein are protein beverages that are thickened, stable, and ready to drink beverages designed for consumption by subjects (e.g., subjects having a need for thickened beverages). In some embodiments, the subjects are subjects having dysphagia.

Experiments conducted during the course of development of embodiments of the present disclosure resulted in identification and optimization of a number of parameters that provide useful protein beverages. For example, it was experimentally determined that intact proteins, with or without gums and protein protection agents, did not result in a beverage with suitable clarity, viscosity, and heat stability. Thus, beverages that utilize hydrolysed proteins were developed. Further experiments determined that beverages comprising apple juice or Konjac gum were typically not suitable. The balancing of multiple factors, the adjustment of one or which can negatively impact others, makes the identification of suitable or desirable protein beverages a significant challenge. Exemplary problems that arose when selecting ingredients and formulation include protein precipitation, product gelling, and under delivery of protein.

Preferred beverages provide one or more or each of 2 to 10 g of complete (e.g., and hydrolyzed) protein per 100 mL serving, an apparent viscosity between 50 cp and 2000 cp, clear (e.g., a turbidity reading from 0 to 1000 NTUs), ready to drink format, approximately 100 kcals of energy per 100 g or 100 mL of beverage, and suitable palatability (e.g., flavor, mouth feel, etc.).

Exemplary compositions and methods are described below.

I. Compositions

Provided herein is a protein beverage with optimized viscosity and turbidity for use by subjects, for example, with swallowing disorders such as dysphagia.

The beverages are not limited to particular sources of proteins. As described above, in some embodiments, hydrolysed proteins are used to provide superior properties. Protein hydrolysates are a mixture of smaller peptide fragments or free amino acids that results when intact proteins are digested in vitro with enzymes. The industrial process is similar to the natural enzymatic hydrolysis of proteins that takes place in the gastrointestinal system during digestion of a protein meal. Hydrolyzed proteins are often more easily digested and absorbed compared to intact protein and free amino acids and can have reduced allergenic potential compared to intact proteins.

Hydrolyzed whey dairy proteins, whey and casein, and hydrolyzed collagen are the most commonly used hydrolyzed proteins, although the present disclosure is not limited to dairy proteins. For example, in some embodiments, hydrolyzed soy, or collagen plus amino acids are utilized.

In some embodiments, the beverages of the present disclosure comprise up to 10% (e.g., 2 to 10 g of complete protein per 100 mL serving), although other concentrations are specifically contemplated. In some embodiments, the whey protein hydrolysate is present at a concentration of 6% to 7% w/w (e.g., 6.3% or 6.6%).

In some embodiments, the beverage comprises one or more gums. The present disclosure is not limited to particular gums. Examples include, but are not limited to, cellulose gum, guar gum, xanthan gum, or a combination thereof. In some embodiments, gums are present in the beverage at a concentration of 0.1 to 2% (e.g., 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.75, 1.8%, 1.9%, 2%, or a fraction thereof).

In some embodiments, the beverage comprises one or more acids or salts. Examples include, but are not limited to, ascorbic acid, citric acid, malic acid, sodium benzoate, sodium citrate, or phosphoric acid. In some embodiments, acids and/or salts are present in the beverage at a concentration of 0.01 to 1% (e.g., 0.01%, 0.05%, 0.1%, 0.5%, 1.0%, or a fraction thereof).

In some embodiments, the beverage comprises a simple or complex carbohydrate. Examples include, but are not limited to, sucrose, glucose, fructose, honey, maple syrup, etc. In some embodiments, the beverage comprises 10-30% (e.g., 10%, 12%, 14%, 16%, 18%, 20%, 25%, 30%, or a fraction thereof) of carbohydrate.

In some embodiments, the beverage further comprises one or more flavorings, coloring agents, or flavor modulators (e.g., modulone). A variety of such agents are commercially available and are suitable for use in the described beverages (e.g., available from Firmenich (Geneva, Switzerland), Sethness (Skokie, Ill.), Wild (Erlanger, Ky.), or other companies.

The beverages described herein provide at least a portion of an individual's daily caloric needs. In some embodiments, the beverage has 50-200 (e.g., 50, 100, 15, 200, or values therein between) kcals of energy per 100 g or 100 mL of beverage.

The beverages described herein provide a beverage with a viscosity suitable for consumption by individual with swallowing disorders (e.g., having dysphagia). For example, in some embodiments, the beverage has an apparent viscosity between 50 cp and 2000 cp (e.g., 50 cp, 100 cp, 200 cp, 300 cp, 400 cp, 500 cp, 1000 cp, 1500 cp, 2000 cp, or a fraction thereof). Exemplary methods for measuring viscosity are described below.

In some embodiments, the beverage is clear (e.g., a turbidity reading from 0 to 1000 NTUs (e.g., less than, 1000, 500, 200, 100, 50, or 10 NTUs)).

In some embodiments, beverages are provided as a thickened liquid or frozen product (e.g., shake, on a stick or other support, cup, etc.).

The beverages described herein are manufactured using any suitable method. Exemplary manufacturing methods are described below.

In some embodiments, hydrolyzed proteins are first blended with water in a stainless-steel tank with constant agitation. Sodium Benzoate is added to the protein solution, followed by a dry blend of one or more acids.

After the acids and salts are completely dissolved in the protein solution, the flavor/color blend is added to the protein solution. The pH is adjusted in steps with 85% phosphoric acid until the solution reaches a pH=3.9. The gums are then dispersed in sucrose and added to the protein solution with high shear mixing.

In some embodiments, solutions are sterilized using high-temperature, short-time pasteurization (HTST, also known as “flash”) or ultra-heat-treating (UHT). In some embodiments, commercially available (e.g., from MicroThermics, Inc., Raleigh, N.C.) sterilizers are used. In some embodiments, sterilized beverages are packaged using aseptic processing or hot fill. In some embodiments, the pH is adjusted to neutral when aseptic packaging is used. Beverages (room temperature or frozen) are packaged in any suitable container. Examples include, but are not limited to, bottles (e.g., screw-top plastic bottles or glass bottles), cups (e.g., with paper or foil lids), stick or other support, etc.

In some embodiments, large scale, high throughput manufacturing is utilized.

In some embodiments, beverages are selected to have desirable consumer palatability. Such beverages may be selected using taste-testing experiments for one or more parameters (e.g., including but not limited to, refreshing (“not at all” to “very”), flavor strength, texture, sweetness, smoothness, bitterness, off-flavor, chalkiness, amount of aftertaste, pleasantness of aftertaste, thirst quenching, or mouth coating). In some embodiments, such testing parameters are used to optimize beverage components.

II. Uses

The beverages described herein find use in a variety of applications. In some embodiments, the beverages are specifically used as a source of hydration and nutrition in subjects with swallowing disorders (e.g., having dysphagia). In some embodiments, subjects are elderly (e.g., older than 65) or not elderly. In some embodiments, the use of one or more servings of the described beverages treats or prevents one or more complications of a swallowing disorder (e.g., including, but not limited to, aspiration on thin liquids, dehydration, or malnutrition). In some embodiments, one or more beverages are administered on a daily basis or as needed.

Beverages can be stored, shipped, and/or provided to end users (e.g., subjects) in any suitable containers. In some embodiments, hot fill and aseptic packaging is employed. In some embodiments, the pH of the material is adjusted to neutral or near neutral and supplied in aseptic packaging.

EXPERIMENTAL Example 1

Methods

This example describes analysis methods used to formulate and characterize exemplary protein beverages.

Rheologic Measurements

Viscosity

Brookfield DV3T controlled stress rheometers, models RV and HA, a water jacketed small sample adapter (SSA), cylindrical sample chamber (Brookfield with defined geometry system for accurate viscosity measurements of small sample volumes in the order of 2 to 16 mL at precise shear rates, jacketed small sample adapter with circulating water pump, and 118 ml vials that were 45 mm in diameter (item #0741-07, SKS Science) were used.

Flow behavior of the samples was measured using two Brookfield DV3T controlled stress rheometers, models RV and HA fitted with temperature controlled small sample adapters and spindle SC4-21 (Brookfield Engineering, Middleboro, Mass.).

Samples with viscosity ranges below 500 cP were measured using model RV, samples with viscosity above 500 cP were measured using model HA.

Samples (7 ml) were loaded using a 10 ml syringe (item #9300-04, SKS Science, West Watervliet N.Y.) and allowed to rest for 3 minutes prior to testing in order to allow for temperature equilibration. Samples were the pre-sheared at 30 s−1 for 3 minutes. A stepped shear test was then run from 200 s−1 to 3.75 s−1, allowing the spindle to rotate 10 times at each step before measurement. Data was then fitted to Power law model using Rheocalc® software to calculate flow (n) and consistency (K) indices (Brookfield Engineering, Middleboro, Mass.).

Yield Stress

Apparent yield stress (σ₀) of the samples was measured using model RV or HA fitted with vane attachment V-71 (Brookfield Engineering, Middleboro, Mass.) submerged to the secondary immersion mark. Model selection was based on the limits of measurable torque ranges for the units: 10% to 100%. The samples were pre-sheared at 20 RPM for 30 seconds, and then a zero torque step at 0.10 RPM was used to ensure a consistent start point for each, allowing torque values go to 0%. Samples were loaded into 118 ml vials that were 45 mm in diameter (item #0741-07, SKS Science). Test speeds (in RPM) were calculated so that the shear rates were as follows: 0.1 s−1 for samples≤500 cP and 1.0 s−1 for samples>500 cP.

Processing

Pilot scale samples ranging from 10 m to 15 kg were prepared in order to test the effect of commercial processing and to prepare enough samples for preliminary shelf life and sensory tests. Special care was taken to ensure the filling temperature did not go above 200° F. When the fill temperature was too high, seam from pockets of ultra-heated beverage caused the formation of foams that made continuous filling challenging. It also resulted in under-filling of the bottles and bottles collapse as the beverage cooled. Foams formed in this way were not stable and dissipated after several weeks of storage. The resulting products were clear.

Shelf Life Studies

Samples of the final prototype SWSL PRB-N-08 were prepared as described above and held under ambient conditions. Samples were pulled weekly for four weeks followed by monthly pulls.

Turbidity Measurements

The clarity (or cloudiness) of a liquid is measured by turbidity. The haziness of a fluid is generally caused by particles that are suspended in the liquid. In thin liquids, large particles generally settle, but in thickened beverages these particles are in a stable suspension and contribute to the cloudiness of the product. Turbidity was measured using a nephelometer that measures the amount of light that reaches a detector set perpendicular to the light source; the more turbid the fluid, the more particles present to scattering the source beam and the larger the reading by the detector. The units of turbidity from a calibrated nephelometer are called Nephelometric Turbidity Units (NTU).

A Hach 2100Q Portable Turbidimeter, silicon oil, lint-free soft cloth, and StablCal® standards were used. Before turbidity measurements, the instrument was calibrated using the StablCal® Standards (20, 100 and 800 NTU). An oiling cloth was used to clean the vials before measurements were taken. The sample cell was inserted into the cell compartment so the diamond or orientation mark aligns with the raised orientation mark in front of the cell compartment. After successful calibration, 15 ml of sample was carefully poured into the provided sample cell. The cell was capped and wiped clean with a lint free cloth to remove water spots and fingerprints. A thin film of silicon oil was applied to the cell to obtain an even film over the entire surface of the cell. The sample was gently inverted and inserted into the instrument cell compartment so the diamond orientation mark aligns with the raised orientation mark in the front of the cell compartment. The lid is closed and the “read” button on the instrument is pushed. Once the reading has stabilized the measurement was recorded.

Exemplary Formulations

A. PRB-N.08

A high protein beverage formula was produced with a protein target of 10 g on 100 g of product and a 100 kilo calories target. For this formulation Xanthan gum was used as a thickening agent. Caramel color was added to resemble the color of typical hydrating beverages. A taste modulator (modulome) from Firmenich was added in order to mask the bitterness coming from the whey protein hydrolysate (WPH). Sodium Benzoate was added as post opening preservative, to prevent mold growth.

Materials and Methods

-   -   Reverse Osmosis (RO) Water     -   Ascorbic Acid     -   Sodium Potassium Meta Phosphate (Benephos)     -   Sodium Citrate     -   Cellulose Gum (CMC 2500)     -   Xanthan Gum (Keltrol T)     -   Whey Protein Hydrolysate (Arla Lacprodan HYDRO 365)     -   Citric Acid     -   Malic Acid     -   Sodium Benzoate     -   Sugar     -   Modulone     -   Phosphoric Acid (85%)     -   Caramel Color, P212     -   Nat Green Apple FLV WONF FAPG958

WPH was blended with water in a stainless-steel tank with constant agitation. Care was taken during the addition to prevent foaming from occurring due to over-blending. Sodium Benzoate was added to the protein solution, followed by a dry blend of ascorbic acid, citric acid, malic acid and sodium citrate.

After the acids and salts were completely dissolved in the protein solution, the flavor/color blend was added to the protein solution. The pH was adjusted in steps with 85% phosphoric acid until the solution reached a pH=3.9. A blend of the xanthan/cellulose gum dispersed in sucrose was added to the protein solution with high shear mixing. Care was taken during the addition to prevent the formation of lumps and fisheyes. The resultant slurry was left to sit for 1-2 hrs to allow the gums to fully equilibrate and hydrate. The apparent viscosity was measured at a 30 s⁻¹ shear rate. If the apparent viscosity was below 1500 cP, it was adjusted by the stepwise addition of 0.01% w/w of additional gum blend. Between each step, the mixture was left to sit for 15 minutes before the viscosity was measured.
